- Remember the days when your internet was connected through the phone line? Oh, that sound of dial-up! We’ve come a long way since then, and chances are that you’re watching this video through Wi-Fi right now. So how did we get here anyway?
In the 1980s, personal computers had begun to enter our lives for good. But at that time, they were connected to the internet through the infamous Ethernet cables. Maybe scientists were getting tired of tripping over all those cables? They decided they wanted to start sending data using radio signals. However, those early attempts were unsuccessful. What scientists didn’t know at the time was that the problem had been solved a decade before PCs were even invented!

SUMMARY:
- The roots of Wi-Fi go way back to the 1940. That’s when a popular Hollywood actress and inventor by the name of Hedy Lamarr came up with a way to prevent radio signals from being tampered with.
- Early attempts were unsuccessful since it all bounced back on walls, furniture, and pretty much anything that stood in a computer’s way.
- It all started back in the 1970s, with electrical engineer Dr. John O’Sullivan, a.k.a. “the father of Wi-Fi.” At the time, he and his team were trying to detect radio signals from distant black holes in space, and they came up with complex equations called Fast Fourier transforms.
- After a lot of experimentation, they took their fancy Fast Fourier transforms, added them in the mixture with the data equations they’d previously tried to send over radio, and thus they formed the basis for the Wi-Fi we all know and love today!
- Later in 1996, they further developed their original key patent, and by 1997 they finally cracked the code and came up with the first version of the 802.11 protocol.
- Wi-fi is a pun for the word Hi-Fi, which means “high fidelity” - a technical term used for high-quality audio technology.
- The frequencies Wi-Fi routers use are 2.4 or 5 Gigahertz per second, which is why data gets transferred so quickly to your phone.
- If you have baby monitors, garage doors, microwaves, cordless phones, and wireless cameras, they can interfere with your Wi-Fi.
- When you turn your phone or computer on and get on the internet, all the information you’d like to access is broken down into binary code. And when you access something through Wi-Fi, then that binary code is transformed into wave frequencies.
- Is Wi-Fi dangerous? Well, the short answer is no. Wi-Fi works at extremely low voltages. Even at short distances, Wi-Fi is just part of the household "smog" that’s generated by TV and radio signals.
- A typical router works at about 100 feet in every direction. As for what can block it, that’s pretty much anything that conducts electricity, like metal, water, mirrors, and even our bodies since they mainly consist of water.

Hey there, BrightSiders, have you ever done digital detox? Would you like to?
First one to reply and like
And im the second one
Which is the best VPN to use?
@@_komaljain NordVPN
For many a Digital Detox nowadays may be impossible, since technology has grown so much and we depend on it much more. Personally I'd hate it lol
I remember when WiFi was still a new thing. People in my school with wifi-capable laptops were like celebrities. 🤣
Wow, I remember when... I don't know when no flip phones came out.
Wow
Hahaha that is so true 😁
Today
Internet : excuse me excuse me please step aside 5G is coming true.
Yes... 😂😂😂
So true

My background is in communications and it's amazing the leap we made from dial-up over copper on a 56k modem to a Gig of Highspeed and WiFi especially over a secured network helped take technology to a whole new level📈
@Axel McCart Thank you👍
Yeah, we used to have internet sent over phone lines, now we have phone lines that work over the internet.
They dealed with complex equation,and we just click once to start it...woah!it's amazing!!!!
That's TH-cam for ya!

IoDizing or IoNizing? I believe it should be ionizing..
Yes it is IONIZING :)
It's old man give him a chance, good point though
I was gon write this
Yep its ionizing
A pretty big error to make in a video on an informational video. Is there a way to edit and reupload videos to TH-cam without losing views and comments?
Hi random person 😄
Who is simultaneously watching the video and also reading the comments 😀
Now plz pause the video and listen to me carefully 😄
Yes you !
I am talking to you!
I wish that you will achieve what you really want to achieve in your life 😄 because you are born to win the game of success of life and you will be very successful in your life 😄
Just you need to note!

*Best and most genuine wishes from a small youtuber 😄*
Awww thanks
😍
I had visited your channel
Your all videos are worth😍
I am your new subscriber 😍
Thank you! (✿^‿^)
There are times when we need a reminder
I appreciate that acknowledgment and I will keep that in my thoughts and actions but my time is coming to an end and I’m so close to my goals I just need a little more time but I’m afraid that I’ll be too late for you and mine. Happiness and Peace, Rest and Relief will come afterwards. Later TH-cam sign guy, “ frequency and the vibration drew this so if you kno what band of the spectrum we are on now , please let me know.
I remember learning about WiFi so I could wirelessly connect my nintendo dsi to the internet router. Crazy to imagine 10 years later WiFi would be a fundamental part of everyday living
Can WiFi be turned off manually on a DS or is it always on?
Hey stop scrolling! 👋
I hope you have a great day, and always love yourself!
Thanks man
Same to you
@@mahirajawat51 same to you..
?.
I know I’m late but thx cus I ducked up today
woah!?!?!?!? how did you know that i was eating popcorn , and the 'HE HE HE' made it much more creepy O-O
Moubin Shaik why?
@Lakshmi Ajay V lol 🤣
😂😂
Weird Haha
Sorry
It's not "Iodizing Radiation"..., it's ionizing radiation.
What he said.
Iodizing radiation. Sheesh.
There's no iodizing radiation, but there is radioactive iodine. Deadly stuff, if your body absorbs it.
@@bxdanny yes, it is a radio isotope of iodine 😄👍
Lol yeah
Bob, from spectrum, told me about this to teach my kiddos. Even my 6 year old was able to learn and enjoy it. Thank you to him for recommending this and to the creators for their video creation. ^_^ This 30 y/o momma and her kiddos learned alot.
I left school BC, "before computers" were even brought in to the classroom. Yes this was in 1981. Family first computer was a Commodore 64 with 38 k memory, and run on an audio cassette to store data. Home computers have come a very long way in such a short space of time.
*And,that's how Mafia, I mean Wifi works*

Wifi: helloo???
Microwave: I'm going to end this man's whole career
WNBT TV why would it?
Bright Side must have broken the record of posting the most videos in a day
A really great video I love how you mentioned Hedy lamarr. I think it's a travesty what little credit she gets for her inventions. And then the radiation ionizing. Keep up the good work!
I am greatly saddened that non-containment includes human body shock location. What is your opinion of the Twitter sound location cover-up? I am prepared for debate. You prepare to win!
It was a duet work between her and another scientist named George Anthel... but he didn't mention his name !!
Hey buddy ♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Yes you !

Yea thanks but this is the most random comment ever
How do creat your own wifi?😂
I'm so addicted to wifi I can't live without it
I'm addicted to devuces such as tv,tablets,phones,ipad,etc.
Coincidentally, I was microwaving popcorn while watching this episode on wi-fi. There was no interference though.
There won’t be unless the shielding in the door is broken, or the interlock fails and allows the magnetron to run with the door ajar. In that case you have bigger problems than losing wi-fi: the microwave oven puts out a million times the power of a phone. It heats the water in food and it will heat the water in your body. And if you have a pacemaker it could interfere with your heartbeat.
Frequency is inversely proportional to time(1Hertz=1/sec)
Ok Einstein thx for ya input
No it's 1ms=1sec
Wanna explain this to me like I’m a 3rd grader?
That dial-up hahahahah ... i will never forget that time lols!
Love your videos I watch them every time
Thank you for the informative video 🙂🙂
Great video, as usual. "ionizing" radiation though, not iodizing.
I’m using wi-fi to watch this video right now. Today it’s an essential for life
This channel is so awesome i love it 😊
Amazing thanks I did learn something new ... great information video ..Thank you for sharing this video I hope you have a nice day
I hope you have a nice day too
Kimberly Kris Mays pegues whats the most informative part?
Yes VERY addicted to Wi-Fi and technology in general. Thanks so much for the video. Love Brightside. Thats why I subscribed. Very informative!!
Ms. Rae what’s the most informative part?
The part about the father of wi-fi and the part about how wi-fi was originally named some decimal number and the marketing team renamed it wi-fi. Love your videos!!! ❤.
really valuable video.Thanks for making such.
This info sick!!!!thanks its the best video ever i seen haaha tnx for the uploader
Why did this video came out after my wifi stopped like 3 hours ago. I came from school and my mom was like the internet is slow, and I was trying to fix it for hours. Turning it on and off, than it finally work!!
Great explanation, thank you guys for the enlightenment
I REALLY APPRECIATE THESE VIDEOS
8:23 You mean to say Ionizing Radiation, Iodine is an element, Ionizing is a process that removes electrons from Atoms/Molecules/Compounds.
may be he mistook it with polarized radiation
@@saikrishnachowdarygariabbai Doubtable. Common Americans who are familiar with Ionizing Radiation, learn of the radiation method when positing whether their Microwaves can cause cancer. Naturally scientists and enthusiasts may learn of it otherwise. I argue that because most Americans would learn of the subject for such a trivial manner, a lack of clarity on the term is more possible than the wrong term. Either way it's still pretty off.
I was just about to drop the same comment, but you beat me to it. Ionizing, not iodizing. Enjoyed the video though!
I've always wondered how wifi worked. I've always wondered that. Now I finally know, and I am indeed amazed by what I have learned. 👌🏻🤙
Also, I actually was wondering if the waves of the wifi levels harmed the body. Good mind reading my guy.
Even though it wasn’t a literal mind reading action, just an accurate prediction. So, good prediction.
I was using dialup long before the internet. You seem to have skipped that. When we first got personal computers we connected with dialup to BBS's and other computer services like Q-Link, AOL, Geenie and others. I remember chatrooms back in the mid 80's. It was a different time.....
Great video, loved it!
Change your wifi name to FBI Surveillance Van
🤣😂🤣😂
😂🤣😂🤣
I am so doing that tomorrow!
Wrong! My first question was... "why don't I get free Wi-Fi :(=" lol
Thank you so much for this great input
Your videos are the best and informative , thanks
Video: This is unavailable at your Country.
Vpn: Am I Joke to You!
Q:How WiFi works?
Me:Saves poor lives😂😂
*lives 😝
Thanks 😂
Thanks so much for sharing 😀🙌🏾
i loves ur video,s it's always gives me something new to learn! Thanks
:)
In 8:11 you are probably referring to "non-ionizing radiation". Nice video!
This! Ionizing, not iodizing! (I think he was thinking of iodized salt).
WiFi stands for “Wireless Fidelity”...
true
Not true. It's "simply a trademarked term meaning IEEE 802.11x."
Michael Papapetros Wi-Fi stands
I didn't know WiFi can stand
It has no meaning
Yes this video was really very informative. Good learning.
One of the most entertaining channels on TH-cam
This video is great and easily understandable, please make more tech videos like this one!!!
Trust me I work for the Government, It's all completely safe...Where have I heard that before?
Thank you bright side. I've learned many interesting things from you.
We are all quite fortunate that we r living in this high-tech world which is created by some genius inventors...
I always wanted to know how wifi works thanks bright side😁👍
Myron whats the best part about its work?
Those of you could see my comment -
May God bless you all.
Edit:OMG! First time I've got so many like's.(Thank you ).
Thanks 😃 same to you
Thanks
THanks same
Are you telling me to bless myself?
@@queenieleoxses7494 I'm not telling you my Dear, Jesus Christ; I'm telling the fellow who is behind you and operating your account.
So many things are confused or simply wrong in this video - it blows my mind!
I love you brightside yall taught me that the notion of wireless fidelity is not what wifi means!!! ❤️❤️
Once I got tripped in WiFi and wife🤣🤣
Sleepers were present on my face then ..
Yeah, I know a lot of people who thought it was pronounced Why - Fee.
If wifi doesn’t exist..
*Welp BOYS were still in the past.*
Very helpful program. Thank you!
I love you and your videos so much
You can only like this if you have internet
You can only watch this if you have eyes
I actually dont have internet
You can comment if you are alive
But I dont
@@ishanapatra9097 then why u are here?? Commenting on TH-cam? 😂
I don’t care how the wi-fi is made all I care about is that it stays here :>
Thank you a tons! I really enjoyed your video.
I know 3 things for sure:
1. Having each residential and commercial unit paying for wifi every month till the end of time is a brilliant capitalist concept.
2. I rarely get headaches. Then I moved. And I constantly got headaches at night and in the morning. At the new place, the Wifi router was 1m from my head. The headaches stopped when I moved the router much farther away.
3. When wifi extenders went mainstream, the newer wifi routers I got were no longer able to provide wifi signal as well thus creating the need for wifi extenders even in a small home.
If not wrong..."Wi-Fi" stands for "wireless fidelity"
It’s also synonymous with WLAN (Wireless Local Area Network)
Thank you for the knowlege
awesome channel and video! Subbed
Thank you, great job
OMG FIRST TIME EARLY IN MY LIFE XD
Umm.. Really? .. Good for u.. . I think? :3
Going to school
Imagine I wake up with 380 sun
You read my mind. Thank you 😊 now I know how it works.💕
Very useful video clip.thanx alot
Something wrong with this channel..only 38k views in 4 hours but 27M subs??
Some people don't care ow wifi works
so it is impossible to have the Internet's version of the Primordial soup theory.
Another nice one. Thanks
"the sound of dial up still hunt me in my sleep"😂😂😂😂😂
All info within the waves looks like same as the akashic records but a different one
Bleu Bullet akashic records? What is that? Sounds occult to me.
Wi-Fi(s) don't work
`coz they are unemployed!
Hehe!
Very useful video, thanks
Thank you to dig in the issue.
WOW i luv u i also subcribed so yah
What do you think about the health risk(s) with 5G? As an electrical/communications tech, I wish the FCC would do more health risk testing before flooding the air. And before its too late🤯
I been asking about that as well. The risk seems relevant and we should have the right to know
I would stand up against it it's awful it's from the enemy to fry our bodies even wifi now makes us sterile 5g is worse get it at your own risk
My Favorite TH-cam Channel.
You make it sound so nice!!
Who are are using WiFi now......hit like
I am watching this video in pakistan with PTCL 4G pocket wifi device
Great video. Thanks 👏
Now I want a video on mobile data
I'm using Sprint's cellular network to watch this. "Unlimited" data is where it's at.
U should get cricket ijs
Isn't it acronym for "wireless fidelity"?
Love this channel
Very interesting video...🤔📽📺😉👍🔝👌
*How Wi-Fi Works:*
1. They don't. They're as slow as a snail
Hey @brightside 🌻
Pls make a vdo on blurry eye-sight & cure on it . I'm counting on ya 👍🙏💚
Emma A are you shortsighted?
BRIGHT SIDE probably , cause sometimes I cannot see clearly whats written on the whiteboard , either way i've to blink rapidly/continuously until my eyes get watery n henceforth this problem is givin me freakin anxiety
thanku so much ...for such kinda info.
apart from the info we all really appreciate the motion graphic artists and illustrators behind the scene and 100000 thumbs up for them! yeah!
